📌 Problem Statement:
You are given a sorted singly linked list. The task is to remove duplicate nodes such that each element appears only once.

👉 The linked list is already sorted, so duplicates will be adjacent.
👉 Try to solve the problem without using extra space.

Example:
Input: Linked List: 2 2 4 5
Output: 2 4 5

Explanation:
In the given linked list, the value 2 appears more than once. After removing duplicates, the list becomes 2 4 5.

🎯 In this video you will learn:
✔ Removing duplicates in-place
✔ Leveraging sorted property of linked list
✔ Efficient O(n) traversal solution
✔ Important interview concept for linked lists
